You want to set INS_HNTCH_FREQ to one of the two peaks. My guess is that the motor peak is actually the second one so about 180Hz? Then set INS_HNTCH_BW to 90Hz (half of the frequency). Does that sound right based on your motor size?
If it does sound right then do the FFT again after you have configured the harmonic notch to see if you need a static notch on the lower peak.
